9. the amount of positive and negative charges a molecule has, and how they interact.
11. a substance that dissolves another substance by pulling the molecules apart through electrochemical interactions.

1. a homogeneous mixture of solvent and solute molecules.Can be liquid, solid, or gaseous.
4. a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. Solid, liquid or gas materials go through it.
5. the tiny particles that are the basic building blocks of all matter.
6. the amount of dissolved solute per volume of solvent in a solution.
8. the study of the chemistry of living things.
10. diffuses through the solvent until the concentration is equal in all parts of the solution.
